Spring集成ActiveMQ配置Spring JMS异步发收消息 ActiveMQ

2.环境

在前面的一篇 ActiveMQ入门实例中我们实现了消息的异步传送，这篇博文将如何在spring环境下集成ActiveMQ。如果要在spring下集成ActiveMQ，那么就需要将如下jar包导入项目：

本文有两篇参考文献，因此有两个实例，项目结构如下图所示：

3.实例1

信息发送者：HelloSender.java

package edu.sjtu.erplab.springactivemq;import javax.jms.JMSException;import javax.jms.Session;import javax.jms.Destination;import javax.jms.Message;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.jms.core.JmsTemplate;import org.springframework.jms.core.MessageCreator;public class HelloSender { /** * @param args * jmsTemplate和destination都是在spring配置文件中进行配制的 * Sender只使用了配置文件中的jmsFactory，jmsTemplate，还有destination这三个属性 */ public static void main(String[] args) { ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml"); JmsTemplate template = (JmsTemplate) applicationContext.getBean("jmsTemplate"); Destination destination = (Destination) applicationContext.getBean("destination"); template.send(destination, new MessageCreator() { public Message createMessage(Session session) throws JMSException { return session.createTextMessage("发送消息：Hello ActiveMQ Text Message2！"); } }); System.out.println("成功发送了一条JMS消息"); }}

信息接受者：ProxyJMSConsumer.java

package edu.sjtu.erplab.springactivemq;import javax.jms.Destination;import javax.jms.TextMessage;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;import org.springframework.jms.core.JmsTemplate;/** * JMS消费者 * 消息题的内容定义 * 消息对象接收消息对象后：接收到的消息体* <p> */public class ProxyJMSConsumer { public ProxyJMSConsumer() { } private JmsTemplate jmsTemplate; public JmsTemplate getJmsTemplate() { return jmsTemplate; } public void setJmsTemplate(JmsTemplate jmsTemplate) { this.jmsTemplate = jmsTemplate; } /** * 监听到消息目的有消息后自动调用onMessage(Message message)方法 */ public void recive() { ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml"); Destination destination = (Destination) applicationContext.getBean("destination"); while (true) { try { TextMessage txtmsg = (TextMessage) jmsTemplate .receive(destination); if (null != txtmsg) { System.out.println("[DB Proxy] " + txtmsg); System.out.println("[DB Proxy] 收到消息内容为: " + txtmsg.getText()); } else break; } catch (Exception e) { e.printStackTrace(); } } }}

客户端：JMSTest.java

package edu.sjtu.erplab.springactivemq;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class JMSTest { /** * @param args */ public static void main(String[] args) { ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext-jms.xml"); ProxyJMSConsumer proxyJMSConsumer = (ProxyJMSConsumer) applicationContext.getBean("messageReceiver"); proxyJMSConsumer.recive(); System.out.println("初始化消息消费者"); }}

Spring配置文件：applicationContext-jms.xml

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd" default-autowire="byName">  <bean id="jmsFactory" class="org.apache.activemq.pool.PooledConnectionFactory" destroy-method="stop"> <property name="connectionFactory"> <bean class="org.apache.activemq.ActiveMQConnectionFactory"> <property name="brokerURL"> <value>tcp://127.0.0.1:61616</value> </property> </bean> </property> <property name="maxConnections" value="100"></property> </bean>  <bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate"> <property name="connectionFactory"> <ref local="jmsFactory" /> </property> <property name="defaultDestinationName" value="subject" />  <property name="pubSubDomain" value="true" /> </bean>  <bean id="destination" class="org.apache.activemq.command.ActiveMQTopic">  <constructor-arg index="0" value="subject" /> </bean> <bean id="messageReceiver" class="edu.sjtu.erplab.springactivemq.ProxyJMSConsumer">  <property name="jmsTemplate" ref="jmsTemplate"></property> </bean></beans>

测试方法：首先运行JMSTest，然后运行HelloSender。

4.实例2

消息发送者： Sender

package edu.sjtu.erplab.springactivemq2;import javax.jms.JMSException;import javax.jms.MapMessage;import javax.jms.Message;import javax.jms.Session;import org.springframework.jms.core.JmsTemplate;import org.springframework.jms.core.MessageCreator;public class Sender { private JmsTemplate jmsTemplate; //getter and setter public JmsTemplate getJmsTemplate() { return jmsTemplate; } public void setJmsTemplate(JmsTemplate jmsTemplate) { this.jmsTemplate = jmsTemplate; } public void sendInfo() { jmsTemplate.send(new MessageCreator() { public Message createMessage(Session session) throws JMSException { MapMessage message = session.createMapMessage(); message.setString("lastName", "ppp"); return message; } }); }}

消息发送客户端：SenderTest

package edu.sjtu.erplab.springactivemq2;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class SenderTest { public static void main(String[] args) { // TODO 自动生成方法存根 ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml"); Sender sender = (Sender) context.getBean("sender"); sender.sendInfo(); }}

消息接收者：Receiver

package edu.sjtu.erplab.springactivemq2;import javax.jms.JMSException;import javax.jms.MapMessage;import org.springframework.jms.core.JmsTemplate;import org.springframework.jms.support.JmsUtils;public class Receiver { private JmsTemplate jmsTemplate; //getter and setter public JmsTemplate getJmsTemplate() { return jmsTemplate; } public void setJmsTemplate(JmsTemplate jmsTemplate) { this.jmsTemplate = jmsTemplate; } /** * 构造函数 */ public Receiver() { } public String receiveMessage() { String my = ""; MapMessage message = (MapMessage) jmsTemplate.receive(); try { my = message.getString("lastName"); } catch (JMSException e) { throw JmsUtils.convertJmsAccessException(e); } return my; }}

消息接收客户端：ReceiverTest

package edu.sjtu.erplab.springactivemq2;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class ReceiverTest { public static void main(String[] args) { // TODO 自动生成方法存根 ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml"); Receiver receiver = (Receiver) context.getBean("receiver"); System.out.print(receiver.receiveMessage()); }}

Spring配置文件：applicationContext.xml
